SASH=HOLDER.

QPECIFICATION forming part of Letters Patent No. 309,300, dated December16, 1884:.

Application filed February 1S, 1884.

To all whom it may concern;

Be it known that I, J AMES F. HAMILTON, a citizen of the United States,residing at Connersville, county of Fayette, State of Indiana, haveinvented certain new and useful Improvements in WVindow-Sash Lock andHolder, of which the following is a specification.

The invention relates to devices for locking and holding window-sashes.Its object is to provide a cheap convenient means to hold the sashes andlook them in any position.

The invention consists of apeculiar arrangement of bolt, case-bolt, andmeans for locking the bolt, whereby either or both sashes may be heldand locked in any position desired, and it will be fully understood fromthe following description of the accompanying drawings, in which- Figurel is a transverse section of aportion of a window-frame and its sashes,taken through the upper sash, and showing my improved locking devicesecured on top of the lower sash. The device is here shown in top planview with the bolt protruded, locking the sashes. Fig. 2 is an invertedplan view of my device with the bolt retracted. Fig. 3 is a frontelevation of the device in the position represented in Fig. 1.

The bolt-case is cast with a circular projection to form a seat for thecam-lever B, which is eccentrically pivoted upon plate or case A by pinb. Upon the upper part of the case is also a ratchet-segment, c, toengage a pawl, C, which is pivoted in the arm of the cam B. The underside of the plate or case A is cast with a groove to receive the shankof the twoarmed bolt D, which is loosely placed within the groove whichit fits, its lower side or bottom being nearly flush with the bottom ofthe case A, so that it will slide freely when the case A is secured uponthe meeting-rail of the lower sash, E, as seen in Fig. 1. The bottom ofthe case is also shelled out in casting, so as to save metal. Upon eacharm of the bolt 1) From (N0 model.)

the top of bolt D projects a segmental stud,

d, to engage the periphery of cam B. By this means the arms of the boltare simultaneously pressed against the frame F and sash G, and

held firmly where placed by the pawl C engaging the teeth of segment 0.lVhen the pawl O is thrown up, the sashes are of course the case andrear of the bolt, and thus throw the bolt back so soon as the pawl isreleased from segment 0.

In Fig. 2 I have shown the buffers d in section,to illustrate how theyare held by theflaring ends of the bolt; but when for additionalsecurity it is desired to have the ends of the bolt-arms enter holes inthe frame and upper sash to lock the sashes firmlyin the closedposition, I make the bolt-arms hollow and fit them with a rubber plug,which projects beyond the end of the bolt to engage the sash G and frameF.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a sash-holder, the combination of the bolt'case, having pivoted ontop a cam-lever to engage a projection on the bolt, and a ratchet andpawl to lock the lever, with a two-arm retaining-bolt, the said armsbeing substantially at right angles to each other, so as to respectivelypress against the windowframe and upper sash when the bolt is shot out,substantially as described.
